+The list of URLs is fed to our private instance of [WebPageTest](https://webpagetest.org) on the 2nd Tuesday of each month.
 
 As of March 1 2016, the tests are performed on Chrome for desktop and emulated Android (on Chrome) for mobile.
 
-The test agents are run from [Google Cloud regions](https://cloud.google.com/compute/docs/regions-zones) across the US. Each URL is loaded once with an empty cache ("first view") for normal metrics collection and again, in a clean browser profile, using [Lighthouse](https://developers.google.com/web/tools/lighthouse). The data is collected via a [HAR file](https://en.wikipedia.org/wiki/.har). The HTTP Archive collects these HAR files, parses them, and populates various tables in BigQuery.
